Create the schema

First, you'll have to write an XML schema file describing the datatypes and XML documents used for communicating with your services.
This example mimics part of a web shop application, where users can create shopping carts and manipulate them.

Messages

For our example, we'll need a factory service for creating shopping carts. It has the following in and out messages:

 <!-- 
  this will create a new shopping cart WS-Resource
  -->
  <xsd:element name="CreateShoppingCart">
    <xsd:complexType/>
  </xsd:element>

  <!-- 
     the response 
     contains an EPR to the new shopping cart
  -->
  <xsd:element name="CreateShoppingCartResponse">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element ref="wsa:EndpointReference"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>

Types used as resource properties

We want to expose the shopping cart as a WSRF resource

<!-- a shopping cart -->
 <xsd:element name="ShoppingCart">
    <xsd:complexType>
        <xsd:sequence>
           <xsd:element ref="test:Entry" maxOccurs="unbounded"/>
        </xsd:sequence>
    </xsd:complexType>
 </xsd:element>
 
 <!-- the current total price of items in the shopping cart -->
  <xsd:element name="TotalPrice" type="xsd:integer"/>

Full schema

The full schema can be found as doc/example/schema/example.xsd in the WSRFlite distribution.
